EASRC (Enhanced Asynchronous Sample Rate Converter) is a new IP module found on i.MX8MN. It is different with old ASRC module. The primary features for the EASRC are as follows: - 4 Contexts - groups of channels with an independent time base - Fully independent and concurrent context control - Simultaneous processing of up to 32 audio channels - Programmable filter charachteristics for each context - 32, 24, 20, and 16-bit fixed point audio sample support - 32-bit floating point audio sample support - 8kHz to 384kHz sample rate - 1/16 to 8x sample rate conversion ratio Signed-off-by: Shengjiu Wang <shengjiu.wang@nxp.com> Signed-off-by: Cosmin-Gabriel Samoila <cosmin.samoila@nxp.com> Acked-by: Nicolin Chen <nicoleotsuka@gmail.com> Link: https://lore.kernel.org/r/260d7a9fbddf9fa90760d30095df60a4c25fd0a1.1587038908.git.shengjiu.wang@nxp.com Signed-off-by: Mark Brown <broonie@kernel.org>
